Hurricane roof suspension system

ABSTRACT

I, James N. Atwood, have invented a new design of and for a Hurricane Roof Suspension System, as set forth in the following specification. The claimed Hurricane Roof Suspension System is to retain the roof to the dwelling in which will enhance the safety of property and life when used. The general purpose of my design is by embedding galvanized cable in concrete poured lintel (or attached by sleeve anchors), over the roof to the other side of the dwelling, with a spacing of 3 foot between cables and attaching the cable of the other side of the roof to the lintel. Where as the length of the cable exceeds 25-30 foot on the roof, galvanized cable or all-thread is attached to the foundation, in walls, up to the roof line, with either galvanize cable and thimble or eye hooks which attaches to the cable on the roof.

SUMMARY OF INVENTION

The general idea of “Hurricane Roof Suspension System” is to retain roof plywood and the trusses to the foundation or block walls.

The advantages by using this method of support for roof structures, is that it will minimize structure damage and loss of property in the dwelling.

This statement of invention is by using cable over the roof plywood which is attached to the trusses and is anchored or embedded in concrete, in the lintel or the slab, in which rebar and concrete are tied into the foundation.

DETAIL DESCRIPTION OF INVENTION

The hurricane roof suspension system starts at one end of the dwelling for new construction and for existing dwelling. The ¼ inch galvanized cable is wrapped around rebar in the lintel (FIG. 101.A) embedded in concrete or is attached to the lintel by ½ inch×4 inch sleeve anchor (FIG. 301.C4),(Pic. 3.2A, 3.2D), with the spacing of 3 foot intervals horizontally between each other (Pic. 1.2A interior left, 1.2C close-up of galvanized cable extruding from concrete lintel). The cable is then extended up ward and around exterior part of the gable (Pic. 1.2B interior right side of lintel with ¼ inch galvanized cable going around exterior gable) through a ¼ inch drilled hole, through the roof plywood on the exterior part of the gable. The ¼ inch galvanized cable (FIG. 201.B1) passes through the support wire eye hook (FIG. 201.B2, 401.D5, 501.E2, 601.G ) with a spacing of 25-30 foot span between the eye hooks in length and 3 foot horizontally to retain the 1.4 inch galvanized cable tension on the roof by means of using the ½ inch all-thread support to roof (FIG. 401.D), which is embedded in the 4 inch concrete slab (FIG. 401.D2) and positioned up ward and extended toward the roof line and is connected to a ½ inch galvanized nuts and lock washers (FIG. 401.D4) and a ½ inch galvanized threaded coupling (FIG. 401.D3) in which the threaded eye hook (FIG. 401.D5, 201.B3) is screwed on to. Which enables only the eye hook to be partly exposed (FIG. 201.B2, 401.D) to permit the ¼ inch galvanized cable through the eye let (FIG. 201.B, 401.D, 601.G, 701.H) and a 25-30 foot maximum interval in length vertically.

Or by means of using the vertical cable support (FIG. 501.E) in which a ¾ inch ‘L’ shape galvanized anchor bolt with a 2 inch closed eye is embedded in 4 inch concrete slab (FIG. 501.E1) every 3 foot horizontally (FIG. 601.G, 601.G1) and 25-30 foot maximum interval in length vertically (FIG. 101.A, 701.H). With the ½ inch galvanized cable (FIG. 501.E4) from anchor bolt (FIG. 501.E1) embedded in concrete floor, up to roof line, is attached by pneumatic crimp sleeve (FIG. 501.E3), with thimble at both ends of cable, with the eye let (FIG. 201.B2, 501.E2) just enough exposed for the ¼ inch galvanized cable to pass through (FIG. 201.B2) it. The ¾ inch ‘L’ shape anchor bolt (FIG. 501.E1) with closed eye can be used in a poured lintel application.

The cross bracing system of existing dwellings (FIG. 701.H) is applied by adding cross bracing every 5 foot (FIG. 101.A, 70.H, 801.J) to the roof suspension system (FIG. 101.A). Where as every 10 foot of cross bracing cable (FIG. 701.H3) is to extend over the peak, down to the other side of the roof, to the last run of ¼ inch galvanized cable and by cross bracing intersection (FIG. 801.J) to give a continuous net approach over the existing roof (FIG. 701.H, 701.H3, 701.H2).

The cable anchoring for existing dwellings (FIG. 901.K) is by adding the ‘L’ shape eye hook every 3 foot across (FIG. 601.G) horizontally and 25-3 foot across in length vertically (FIG. 101A, 701.H) into existing walls by installing (2) ½ inch×3 inch sleeve anchor n the slab in the existing walls to he vertical cable support (FIG. 501.E).

The ¼ inch cable on the roof to the other end of the dwelling, penetrates back down behind the trusses (Pic. 2.1D, 2.1C) and down to the existing lintel (FIG. 101.A, 301.C). This attachment to the lintel in detail (FIG. 301.C4) has a pass through of the lintel which is incorporated as a fail-safe-design (FIG. 301.C2). by which if the crimp sleeve slips, the cable (Pic. 3.2A) will only surrender ¾ inch to 1 inch (FIG. 301.C1) in the loop only. The stopper (FIG. 301.C2) will not pass through the sealed lintel. The lintel pass through (FIG. 301.C3, 301.C4) is a 9/16 inch hole and filled with simpson epoxy ET-22 (Pic. 3.2A face view, 3.2 B down ward view, 3.2D close up of pass through with stopper (FIG. 301.C2)), the lintel has a ½ inch×4 inch sleeve anchor with a 1¼ galvanized washer ad a ½ inch galvanized nut (FIG. 301.C5), the threads on the ½ inch sleeve bolt have had simpson epoxy ET-22 applied to them both to retain tightness and will not loosen by vibration.
